RICHARD F. WILSON, OF STOCKTON, CALIFORNIA.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 324,284, dated August 11, 1885.

Application filed February 2, 1885.

To all whom it may concern.-

Be it known that I, RICHARD F. WILSON, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Windmills, of which the following is a specification, reference being had therein to the accompanying drawln gs.

Figure 1 is a side elevation. Fig. 2 is a view of the top with wheel and shaft removed. Fig. 3 is a section of the pitman and-its standard and shaft. Fig. 4 is a view of my improved spring. Fig. 5 is a view of a portion of the tail and turn-table. Figs. 2, 3, 4, and 5 are enlarged views.

Similar letters of reference indicate corre sponding parts.

My invention relates to certain improvements in that class of windmills termed selfregulators.

It consists, first, in providing a small turntable and improved spring, so as to easily control the position of the wheel to the wind; second, in a simple and cheap method of hanging the tail; third, in such other devices as will be described in the specification, and specifically pointed out in the claim.

The invention will first be described in connection with the drawings, and pointed out in the claim.

The vertical frame of my mill consists of the posts A, A, A and A These support just below the wheel the platform A and at their tops the turn-table bed B.

G is the tail secured to a vertical gaspipe, O, which is rigidly secured to the turn-table 0.

C is a flanged bushing that is set in the top of the gas-pipe O to support the tail 0. A plain bushing, 0 is also inserted at the foot of the gas-pipe G. A rod, 0, is inserted in gas-pipe O and its bushings O and 0*, and connects the tail 0 thereto.

D is the wheel of the mill, attached to a crank-shaft, a, which connects with a pitman, I), which is attached at its upper end to a standard, a, which is pivotally attached to a timber, G, of the frame, and has its other end connected to vertical pitman e, which eX- (No model.)

tends downwardly through the turn-table G and bed 13, and through a guide, f, attached to post A of the frame, and is attached by swivel to the pump-plunger. g is a sleeve on pitman 0, having a regulating-chain, z, passing upwardly through the bed B and turn-table C over properly-located rollers and connecting with the tail O.

h is an angle-rod attached to sleeve 9, and has at its lower end a cord or wire connecting it with hand-leverj.

F, F, G, and G are the top timbers of the mill, F and F resting upon and bolted to the turn-table O resting upon its bed B. When the wind is light, the tail C is held at right angles to the wheel D by means of my improved spring E, which is embraced in the tines of two forks, E and E, by pin E The stem of fork E is attached to timber F near timber G, and the stem of fork E is connected with the tail 0 by a chain, E.

Onthe ends of the timbers F G are tailstops, for the purposes their name indicates.

The pitman b has a forked head, I), holding by bolts or other means wooden boxing 21 which engages crank-shaft a. The upper end of pitman b engages with its supporting-standard c, which is pivotally secured to timber G, as before shown, attached to timbers F and F. A guide, d, is attached to timbers F and F, and engages with standard 0 to prevent its moving laterally and to hold it steadily in position.

\Vhen the mill is running with sufficient wind, the spring E will keep the tail in a line behind the wheel; but a strong wind will act upon the tail and wheel, forcingthe mill around, overcoming the resistance of the spring E, which in a light wind, as shown, keeps the tail directly in a line behind the wheel. The spring E therefore acts to keep the wheel in the wind when the wind is light; but in a strong wind the spring E yields and the tail, turning with rod 0* in gas-pipe O,throws the wheel out of the wind. j theltail may also be turned around and the wheel turned out of the wind.

As many of the features shown in the drawings are not new, I have not referred to them, except to connect them with what is novel.

What I claim, and desire to secure by Letarm which has connection with the said toil, ters Patent, is substantially as and for the purpose specified. 1
